Air quality of Kathmandu Valley, the capital of Nepal, was one of the worse among the big cites in the world. The air quality situation was becoming more critical due to the substantial increase in the conventional fueled vehicles in the valley each year. The bowl-like topography and generally low speeds of wind during the dry seasons create poor dispersion conditions, augmenting the air pollution problem further. The pollution is expected to quadruple by 2020 from the 2005 level in as business as usual scenario.
